This article describes how to delete an iteration in a project.
If the iteration that you want to delete is closed, you will need to first click on Show closed iterations to include the display of closed iterations.
Then, select the iteration to be deleted. The iteration Properties will display in the right-side pane.
To delete the empty iteration, click Delete.
If the Delete option is grayed out, the iteration either contains issuesor you do not have "Change" rights to the project. In the below example, there are 4 issues in the "Backlog" iteration. Those will need to be unassigned from the iteration before it can be deleted.
|Note: If ALL iterations are deleted, the use of iterations will be turned off for the project.|
